The sub-shell are 3 d, 4 d, 4 p and 4 s, 4 d has highest energy as n+ℓ value is maximum for this.

Q. For which one of the following sets of four quantum numbers, an electron will have the heighest energy?

$n - 3, l - 2, m - 1, s - 1/2$

$n - 4, l - 2, m - - 1, s - 1/2$

$n - 4, l - 1, m - 0, s - (- 1/2)$

$n - 5, l - 0, m - 0, s - (- 1/2)$

The sub-shell are $3 d, 4 d, 4 p$ and $4 s, 4 d$ has highest energy as $n + ℓ$ value is maximum for this.

Q. For which one of the following sets of four quantum numbers, an electron will have the heighest energy?

n−3,l−2,m−1,s−1/2

n−4,l−2,m−−1,s−1/2

n−4,l−1,m−0,s−(−1/2)

n−5,l−0,m−0,s−(−1/2)

The sub-shell are 3d,4d,4p and 4s,4d has highest energy as n+ℓ value is maximum for this.

$n - 3, l - 2, m - 1, s - 1/2$

$n - 4, l - 2, m - - 1, s - 1/2$

$n - 4, l - 1, m - 0, s - (- 1/2)$

$n - 5, l - 0, m - 0, s - (- 1/2)$

The sub-shell are $3 d, 4 d, 4 p$ and $4 s, 4 d$ has highest energy as $n + ℓ$ value is maximum for this.
